Rooms were dirty, pull out couch was clearly not changed or cleaned. Smoke detector was actually pulled out of ceiling and missing. Crazy when we all actually had to leave building or room up main floor due to fire alarms going off. They could have mentioned when we booked, no liquor license and could not serve in restaurant or hotel. Just run down and needs more help and upgrades but kids had fun, so we made best of it.

My kids loved this place, the arcade and water park was a lot of fun! Room was clean, con was that there was no alcohol sales during our stay due to new management and waiting for liquor license.The water park needs updated but still a lot of fun. If it wasnt for that would of given 5 stars.

Overall the hotel was better than the reviews. Waterpark needs some painting but kids don’t care. Beds were comfortable with rooms very clean. A full breakfast was nice with a large family. Very accommodating with kids activities in and out of the waterpark area. Front desk was very nice and helpful. They put our family all together which made the trip even more fun and convenient with small children
